The Double Eye Rocker Type - Galv - 3500kg - 50mm wide - Pair isn’t just a part; it’s a deliberate upgrade to how a trailer carries and cushions its load. Built with galvanised durability and designed to keep four wheels evenly engaged, this suspension system delivers a noticeably smoother ride on rough roads, busy work sites, or when transporting equipment where stability matters most.

Why this rocker suspension stands out

Trojan Rocker Tandem Suspensions use a rocker bar that pivots on a central hanger, distributing the weight evenly across all four wheels. The Double Eye design provides reliable articulation at both ends, letting the springs flex independently while maintaining trailer control. The galvanised frame option (T8718GALV) adds corrosion resistance for long-term performance in varying climates and environments.

Core benefits at a glance

• Balanced loading: Evenly distributes load to all four wheels, reducing axle stress and improving stability on uneven terrain.
• Durable, corrosion-resistant build: Galvanised frame version enhances longevity in exposure to moisture, salt, and outdoor use.
• Versatile mounting: Available as a weld-on kit for direct trailer chassis integration or pre-assembled on an angle iron frame for quicker installation.
• Heavy capacity: Designed for up to 3500kg per pair, making it ideal for horse floats, livestock trailers, and heavy-duty utility trailers.
• Clear fitment options: Multiple configurations (unmounted, mounted, assembled; galvanised frame option) to suit your trailer setup.

Specifications and configuration options

• Capacity per pair: 3500kg
• Width: 50mm mounting footprint
• Finish variants: Bare steel (unmounted or mounted & assembled) or galvanised frame (mounted & assembled)
• Kit vs assembled: The kit can be welded directly to the trailer chassis or supplied assembled on an angle iron frame. Note: The frame is not included with the kit.
• Note on hardware: Does not include axle U-bolts or plates.

Who benefits most

This suspension is ideal for trailers and floaters that demand a superior ride and dependable performance under load. It’s particularly well-suited for:

• Horse floats and equestrian trailers needing a smoother, more controlled journey for both animals and riders.
• Livestock trailers where even weight distribution reduces tire wear and improves handling.
• Rugged or off-road work trailers that regularly encounter rough surfaces or uneven ground.

Installation and setup tips

Choose the mounting approach that fits your project:

• Welded-on kit: Weld directly to the trailer chassis for a permanent, rigid installation. This is a common choice for builders who want a tidy, integrated suspension system.
• Assembled on angle iron frame: Opt for a ready-to-install assembly on an angle iron frame for a faster retrofit or where framing is already in place.
• Frame compatibility: If you select the galvanised frame variant (T8718GALV), you’ll have a corrosion-resistant option ready to bolt into your trailer setup.

Remember, the kit doesn’t include the frame, and axle U-bolts or plates are not included in any option, so ensure you have the appropriate hardware on hand during installation.

Practical insights and maintenance

For longevity and consistent performance, inspect the pivots and mounting points periodically, particularly after heavy use or on corrosive environments. Keep connections clean and lubricated as recommended by your trailer builder to maintain smooth articulation of the rocker bar. If you’re upgrading from a less advanced suspension, you’ll likely notice improved ride quality, reduced trailer sway, and better weight distribution across all four wheels.

With the Double Eye Rocker Type - Galv - 3500kg - 50mm wide - Pair, you’re choosing a purpose-built solution that combines robust galvanised construction, thoughtful engineering, and practical installation options—delivering a safer, more comfortable towing experience for your trailers and the loads you carry.
